COAL-OIL STOVE.

SPECIFICATION forming part of Letters Patent No. 254,529, dated March 7,1882'.

' Application filed January 11, 1882. (No model.) I

To all whom it may concern:

Be it known that I, GEORGE W. BILLINGS,

of Cleveland, in the county of Ouyahoga and State of Ohio, have inventeda new and useful Improvement in Coal-Oil Stoves, of which the.

companying drawings, in which- Figure '1 is a perspective view. Fig. 2is a vertical section. Fig. 3 is a plan view of middle plate, showingburner-openings and the slides for closing same. Fig. 4=is abrokensectional view of part of the lower portion, to show internalconstruction. Fig. 5 is a detached view of the oil-reservoir.

A'is the lower or base frame, provided with feet at the four corners.

A represents the side walls of the lower portionof the stove, whichincloses the oil-reservoir B, leaving space around and under the same.

G is a middle or central plate or diaphragm, supported upon the saidwalls A, and has four square openings, 0 0, located in the central partof the four sides. The central part of said plate 0 has a square plate,O,located between the said four openings 0 c and slightly raised abovethe level of the main plate 0, supported at its four corners byprojections c.

D is a" square pot, having a square central flue, d, and is suspendedunderneath and to the middle plate, 0, with the said central fluedirectly underneath the said central raised plate, 0. The space in thepot D surrounding the central flue, d, is divided into four separatechambers, E, by means of four loose angle-plates, held in place againstthe sidesot' the walls of the flue d by an open diaphragm, k. The wallsof the pot and its flue are made slightly slanting, so that the saiddiaphragm is fits a short distance from the top, where it is supported.The lower part of the walls of the chambers E are perforated, to make acommunication between said chambers and the outer space in the pot D,for a purpose hereinafter shown.

The four openings 0 c in the central plate, 0, are provided with slidinglids or covers F, sliddows to enable the flames to be seen.

ing in rabbets in the sides of the said openmeets with and saturates theashes through the perforations.

The top portion of the stove consists of a dome-shaped chamber, Gr,surmounted with a plate, H, having a central opening, I, oventhe flames,and is provided with studs 'or projections h, upon which to setcooking-vessels and allow the heat to circulate thereunder. The sides ofthe dome are provided with mica win- The top plate is supported at thefour corners by rods it. The dome is also attached to the plate 0 at oneside by hinges, which enables the dome to be turned over, whendesired,for supplying the pot with oil or other purposes.Slot-openingsjj are made below the mica Windows for the admission of airabove the central plate or diaphragm, O.

The object of constructin g the stovein square form is to enable flamesto be controlled and regulated in a much more convenient and perfectmanner. By this arrangement the slides or valves F, beingstraight-sided, can be adjusted over the flames more or less, as may berequired, for regulating the volume of flame, and also enables theshutting off entirely of one or more of the flames or burners. Bycovering'the central flue, d, with the central plate, 0, the draft ofair, striking the under side of said plate, is diverted in horizontallines, and meets the flames horizontally through the open ings at theedges of said plate in opposition to the currents of air from the sideopenings, g, in the dome, thereby producing a perfect combustion.

The operation of this stove is as follows: The Pet 1) being suppliedwith oil, as aforesaid, the plate or diaphragm 7c is placed over theoil, which protects it and prevents anything from falling into it. Theashes become saturated with the oil through the aforesaid perforations,and the oil is burned on the top surface of the ashes.

To light the stove, the top G is thrown back and the slides F withdrawnfrom over the ashchamber; then with a lighted match or torch the oil maybe set on fire at the surface of the ashes. The dome G is then turneddown again. The draft of air through the central flue, d, supplies theflame with a sufficient amount of oxygen, causing the oil to burn with apale blue light without smoking. Air is also admitted through the slots1, which counteracts against the draft from the central flue and directs"the flames upward toward the central opening in the top plate, H. 7

With the use of ashes instead of the ordinary wicking there is nocharring, because there is nothing consumed but the vapors of the oil,and by the peculiar arrangement of feeding the flames with air there isno carbonization, but a complete consumption of the elements of the oil.A

Having described my invention, I claim as follows: 25

1. The square pot D, having square central flue, d, and provided withthe perforated ashchambers E, and the diaphragm is, comprising theoil-fount of an oil-stove, substantially as described. 30

2, The combination, with the pot D, comprising the oil-fount abovedescribed, of the plate (3, having the openings 0 0 over the ashchambersE, and also having the raised central plate, O,over the'flue d, andprovided with 35 the sliding plates F for regulating the flames,substantially as described.
